Span beat the throw to second, but second baseman Scooter Gennett's relay throw got Rendon at first. However, second base umpire Angel Campos called Span out for obstruction as Span came up into Gennett after his slide.

Nationals manager Matt Williams came out to argue, and the umpires met behind second base as Williams hovered.

Span remained out but Rendon was ruled safe at first because Span's obstruction created a dead-ball situation. Crew Chief Bill Miller explained to the call to Brewers manager Ron Roenicke before play resumed.
